摘要
需求工程是系统开发的初始阶段,其目的是得到关于客户问题的准确、清晰、一致的描述以及相应的求解限制。尽管人们已经认识到需求工程的质量影响到整个系统开发的成败,但开发人员在需求工程阶段所得到的支持却最少。本文从需求工程的基本概念出发讨论了需求工程的主要问题以及现有研究工作,并试图从领域、语言、模型及解释四个方面来讨论关于需求工程质量及其研究成果。
Requirements engineering is the initial phase of system development. It is our aim to formulate an aceurata, concise and consistent description of client's problem and corresponding constraints on the solution. Although we generally accept that the quality of requirements engineering has great effects on the success or failure of a project, the system developers usually find themselves with little support in this phase. This paper gives the fundamental concepts, activities, problems, and current research efforts of requirements engineering. Also, we discuss the quality and research results of requirements engineering through the four aspects of conceptual modeling: language, domain, model and interpretation.
